I spent three to four weeks with the iQOO 15, using it as my main phone for daily communication, gaming, media and photography. The iQOO 15 arrives with an aggressive spec sheet, pairing the Snapdragon 8 Elite Gen 5 with iQOO’s self-developed Q3 e-sports chip, a 7,000mAh Blue Ocean battery, and a new 2K 144Hz Samsung LEAD OLED panel. But on top of the hardware, iQOO is clearly positioning this device as a performance flagship that also aims for a well-rounded everyday experience. After extended use, here is how it held up.
4Performance and experience (2/2)
Battery life is outstanding. The massive 7,000mAh battery comfortably lasts a full day with heavy gaming or nearly two days with lighter use. On busy days with navigation, photography, streaming and a few gaming sessions, I usually ended with 25 to 35 percent left. For many users, this battery may be the strongest reason to choose the iQOO 15.
Charging is equally impressive. With the bundled 100W charger, the phone goes from nearly empty to 25 percent in around 10 minutes, passes 75 percent at roughly the half-hour mark and reaches full around 49 minutes. Wireless 40W charging is available and works consistently with standard Qi pads and iQOO’s own chargers.
It’s the first iQOO phone to come preloaded with the OriginOS 6-based Android 16. The overall user experience is fluid, and it comes with the promise of five years of Android OS upgrades and seven years of regular security patches. Day-to-day stability is excellent, and animations are smooth throughout.
